SPECIFICATION forming part of Letters Patent No. 414,398, dated November 5, 1889.

. Application filed February 25, 1889. Serial No. 301,081. (No model.)

To all whom it may concern:

Beit known that 1, JOSEPH @Ass GooDRroH, of Grinnell, in the county of Poweshiek and State of Iowa, have invented a new and Improved Tank-Heater, of which the following is a full, clear, and exact description.

The object of nay-invention is to improve the ordinary form of tank-heater shown in patent to F. Funk, No. 286,805, October 16,

The invention consists in the construction and arrangement of parts, all as will be hereinatter more fully explainechand specifically pointed out inthe claim.

Reference is to be had to the accompanying drawings, forming a part of this speciication, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a central sectional elevation of a tank-heater embody-ing my improved construction. Fig. 2 is a central sectional elevation of the tire-pot; and Fig. 3 is a sectional plan view of the {ire-pot, the grate, however, being removed.

In the drawings, 10 represents the drum or body of the heater, to which drum or body there are connected ears or lugs 11, adapted to fit upon the edges of the tank in connection with which the heater is to be employed or to rest upon beams supported by said tank d edges.

In connection with the drum-body I provide a cap or cover 12, that is provided with a smoke-stack 13 and formed with an aperture adapted to receive an ai r-ue lehwhich is connected to the grate 15 and leads downward to the ash-pit beneath the grate, the supply of oxygen necessary to maintain proper combustion entering through this flue. The grate 15 forms the bottom of the tire-pot, the side walls of such pot being composed of a sheet-metal casing 16, to which there are riveted legs 17 and 18, the legs 17 extending upward beyond the upper edge of the casing 1G, there to be engaged by a bail 19, all of the legs extending below the lower edge of the casing, so that said lower edge is elevated some distance beyond the bottom of the drum or body 10.

'J ust below the lower edge of the casing 16 the legs 17 and 18 are provided with inwardlyextending lugs or projections 20, upon which the grate l5 rests, there being a space a between the upper face of the grate and the lower edge of the casing.

Vith such a construction as the one above described it will be seen that should the fire built in the tire-pot (made up, as hereinbefore set forth, of the casing 16 and the grate supported by the casing-legs) become low and need attention -the cover 12 may be taken off and the tire-pot removed bodilyfrom the drum or heater-body, the opening a providing for the removal ot' any cinders or clinlters which may have been formed, and a few moments in the open air serving to thoroughly revive the fire.

The advantages of this construction will be apparent to those having had occasion to use the old form ot' tank-heater, wherein the repot is formed of the side walls of the drum or heater-body and a grate that is supported above the bottom of said body, no way for removing the grate without dumping the iire being, however, provided.

Although I have illustrated and described a cylindrical fire-pot, I desire ity to be understood that the fire-pot could be tapering and narrower at the bottoni than at the top. y

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the outer drum or body 10, provided with support 1l and a rcniovable cover having a smoke-outlet tube 13, of the removable fire-pot consisting in the casing 1G, the legs 17, secured thereto and having projections QOabove their lower ends, the grate rest-ing on said projections and the bail 19, and an air-inlet tube leading into the lower end of the druni or body below the grate, substantially as set forth.
